Interpretation Introduction

Interpretation:

Curved arrows are to be drawn, and the product of each electrophilic addition step is to be shown where the nitro (NO2+) group adds to phenol to yield three nitro substituted phenols.

Concept introduction:

The curved arrow notation keeps track of electrons in an elementary step. Curved arrows are drawn from the electron rich to electron poor sites. An electrophilic addition step occurs when a species containing a non-polar pi bond (as part of a double or triple bond) approaches a strongly electron-deficient species (an electrophile). A new bond is formed between atoms of the pi bond and the electrophile. The product of each of the electrophilic addition is a carbocation, which is highly unstable and will react further because it has a positive charge and lacks an octet.

Draw a mechanism for the reaction of methylamine with formic acid. In the box to the left, draw any necessary curved arrows. Show the products of the reaction in the box to the right. Include any nonzero formal charges and all lone pairs of electrons. Finally, check the box to indicate which side of the reaction is favored at equilibrium.
In the electrophilic addition step shown here, where NO; adds to phenol, the electrophile can add either ortho, meta, or para to the OH substituent on the ring. Draw the curved arrows and products of each electrophilic addition step. OH Ortho ONO2 ? Para Meta Phenol
Curved arrows are used to illustrate the flow of electrons. Follow the arrows and draw the intermediate and product in this reaction. Include all lone pairs. Ignore stereochemistry. Ignore inorganic byproducts.
